ABSTRACT

A lamination for a dynamoelectric machine wherein the slots include a pair of sides, one of which sides is straight and the other of which is stepped. The slots are so designed to receive a prewound coil.



1. A lamination for dynamoelectric machine comprising a substantially circular stamping having slots extending inwardly from the outer periphery thereof, said slots defining teeth on said lamination, said teeth being of alternate configuration, one of said teeth having substantially parallel sides and, the other of said teeth having stepped sides.
 2. A lamination for a dynamoelectric machine as defined by claim 1 wherein the vertical sides of said other of said teeth are substantially parallel to the sides of said one of said teeth.
 3. A lamination for a dynamoelectric machine as defined by claim 1 wherein the inner widths of said alternate teeth are substantially equal.
